    Sammanfattning : In mobile communication new applications like wireless internet and mobile video have increased the demand of data-rates. Therefore, new more wideband systems are being implemented. LÄS MER

  3. 17. Active Distributed Power Systems Functional Structures for Real-Time Operation of Sustainable Energy Systems

    Författare :Jörgen Svensson; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automation; Distributed power systems; RES; Power electronics; Energy management system; Real-time operation; Advanced functions; Communication; Elektronik och elektroteknik; Electronics and Electrical technology; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : Present power system will face great challenges in several areas depending on the market economy, extensive global integration and constant need for more electric power, which will force the system to operate much closer to its stability limits. Meeting these challenges may involve improving and complementing or even total restructuring of the power systems. LÄS MER

    Sammanfattning : The aim of this thesis has been to analyse how savings banks were integrated into the Swedish financial system from the end of the 19 th century until 1968. The study has focused on two questions. LÄS MER

  5. 19. Dialogues on the Net - Power structures in asynchronous discussions in the context of a web based teacher training course

    Författare :Annette Johnsson; Utbildningsvetenskap; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; minority; cultural background; sex; ethnicity; gender; age; socio-economic; dialogicity; web based; computer based; CMC; net based; asynchronous; CSCL; teacher education; power structures; dialogues; Group work; team work; symbolic capital; group work;

    Sammanfattning : The general aim of this thesis is to investigate the interaction processes that occur in group dialogues when teacher students work in small groups, using net based asynchronous dialogues to solve a problem in the area of environmental sustainability. More specifically, the interest is to determine whether students’ net based dialogues give rise to patterns of dominance/subordination similar to those observed in face-to-face situations. LÄS MER

  7. 20. Moisture Conditions and Frost Resistance of Concrete in Hydraulic Structures

    Författare :Martin Rosenqvist; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydraulic Structures; Hydro Power; Concrete Dams; Concrete; Frost Resistance; Scaling; Spalling; Moisture Absorption; Macroscopic Ice Lens Growth;

    Sammanfattning : Owing to the winter conditions in Sweden, the effects of frost action may have a considerable impact on the deterioration of concrete. Both superficial and internal damage, which are suspected to have been caused by frost action, have been found in concrete in hydraulic structures. LÄS MER
